Superior RF Transparency, Weather Resistance, Tactical Finishes and Customization

Our heavy-duty fiberglass enclosure is specifically designed to provide excellent transparency for RF signals, ensuring zero compromise on your high-power broadband antenna operation. The specialized cylindrical design serves a dual purpose: it significantly reduces wind loading to withstand extreme wind forces and minimizes the disruptive effects of ice formation. This thoughtful engineering not only protects the internal components but also provides an aesthetically pleasing, low-profile appearance for strategic deployments.

Built for field readiness, all of our GPS band helical antennas come standard with a tactical olive green MIL color finish, seamlessly integrating into defense and ground control environments. Understanding that operational requirements vary, we also offer fully customized housing and radome color options upon request to meet your specific mission parameters.

Key Technical Highlights of GPS Jammer Anti-Jam GPS Antenna:

Broadband Coverage: Both series operate across the 1100-1700 MHz band. This allows a single antenna to cover GPS (L1–L5), GLONASS, IRIDIUM, and INMARSAT without needing multiple units.
Military Ruggedization: Designed to MIL-STD-810G standards. The use of Teflon Dielectric Transmission Lines is a specific design choice to ensure the antenna can handle high power without thermal breakdown or VSWR spikes.
Environmental Survivability:
- Wind & Ice: The cylindrical radome shape is intentional; it reduces wind surface area and prevents ice buildup from distorting the signal pattern.
- Finish: Standard Olive Green (MIL color) for tactical concealment, though custom colors are available.
Flexible Deployment: The AH-1117-9, AH-1117-11, AH-117-13 and AH-1117-16 models includes a dual-axis mounting system, allowing for 360° Azimuth and 90° Elevation steering, which is critical for tracking drones or aircraft.

Rugged, All-Weather Enclosures

All our high-gain, circular polarized helical antennas are fully protected by a high-tech, ruggedized radome. Crafted from high-strength fiberglass and UV-resistant ABS materials, these enclosures guarantee survivability in the harshest environmental conditions.

Minimal Wind Loading: The cylindrical design minimizes wind resistance and prevents ice accumulation.
Maximum RF Transparency: Ensures uninterrupted signal transmission without sacrificing structural integrity.
Customizable Finishes: Supplied in a standard olive green MIL finish, with customized colors available upon request.

Types of High-Gain GPS Jammer & Anti-Jam Ground Control Antennas

Antenna Experts manufactures industry-leading, military-grade GPS jammer and anti-jam ground control antennas. Designed to meet MIL-STD-810G specifications, our directional helical and omni-directional quadrifilar helix antennas deliver unparalleled performance for critical defense applications, including UAV/drone spoofing, ground-to-air communication, and broad-spectrum surveillance.

Quadrifilar Helix Circular Polarized Omni Antennas (QHA-1117 Series)

The QHA-1117 is a highly versatile, broadband omni-directional antenna available in LHCP or RHCP configurations. Covering the entire 1100-1700 MHz frequency band, it operates seamlessly across GPS L1 through L6, IRIDIUM, GLONASS, and INMARSAT bands without requiring multiple antennas.

Design: Features two twisted vertical loop radiating elements utilizing a specialized "Teflon Dielectric Transmission Line" for high power handling.
Convenience: Compact size allows for easy handling and shipping; requires no field tuning.
Mounting: Includes stainless steel hardware and a NATO mounting flange for ultimate weather protection.

Directional Circular Polarized Helical Antennas (AH-1117 Series)

Our AH-1117 series (available in 9, 11, 13, and 16 dBic gain options) provides wideband directional transmission and reception using advanced Circular Polarization Antenna Technology. This allows for superior signal penetration through interference and obstructions. Customized 21dBic circular polarized directional helical antenna is also available which was supplied to US Air Force for one of their project.

Compact Power: Smaller than conventional Yagi antennas while delivering superior, wide-beam performance.
Complete Articulation: The AH-1117-9 model includes a specialized mount allowing for 360-degree azimuth steering and 90-degree elevation adjustments.

All GPS Bands 10dBi Vertical Omni Antenna (JCN10-1117)

The JCN10-1117 is an ultra-high-performance Broadband Collinear Antenna specifically engineered for simultaneous transmitting, monitoring, and jamming across the entire GPS spectrum (1100–1700 MHz). Designed to provide comprehensive area denial or surveillance coverage, this antenna eliminates the need for multiple narrowband arrays. Enclosed in a ruggedized ABS radome and utilizing 6063T6 aluminum, the JCN10-1117 is optimized for fixed stations, maritime platforms, and tactical mobile units operating in severe environmental theaters.

Tactical Construction & Signal Purity

Hardened materials for zero-failure performance in mission-critical applications. The JCN10-1117 features vertically stacked radiating elements that are fully welded at every junction. This architectural precision prevents mechanical loosening and RF inter-modulation (IM), ensuring the highest signal fidelity during high-power signal denial operations. The internal array is completely protected within a high-strength, UV-resistant ABS radome, providing superior RF transparency and structural rigidity. The cylindrical design minimizes wind loading and reduces ice accumulation, ensuring stable boresight performance.

Operational Efficiency

True broadband saturation with consistent pattern stability. Unlike antennas that require tuning, the JCN10-1117 uses specialized impedance matching to maintain constant performance across the full 600 MHz bandwidth.

High-Gain Saturation: Delivers a peak gain of 10 dBi, concentrating energy effectively across the GPS bands.
Narrow Vertical Beamwidth: The 18-degree vertical aperture focuses the majority of the 200-Watt power capacity toward the horizon, maximizing the effective range for both jamming and interception.
